I could reproduce something like this with
Question wrapper = "Panel wrapper"
Which setting did you use?
You can do this either by
Code:
<style>
.panel-body { padding: 0rem;}
</style>
or of course
Code:
<style>
.panel-body { display: none;}
</style>
You see, it's always the same procedure.
Investigate the page with a webdevelopment tool, that is included in each modern browser
(Chrome: CTRL-SHIFT-I, Firefox: F12)
and see which classes are affected.
Here you may try to see what happens if you chande some settings.
